Description

Technical Field

[0001] This utility model relates to the field of scrubbing tower technology, and in particular to an inlet gas distributor that prevents backflow of water in a scrubbing tower. Background Technology

[0002] A gas scrubbing tower is a new type of gas purification equipment. It is an improvement upon the floating packing layer gas purifier and is widely used in pretreatment for industrial waste gas purification and dust removal, achieving excellent purification results. For coal gasification processes, gas scrubbing is unavoidable; this unit operation is used regardless of the coal gasification technology. Because its working principle is similar to a washing process, it is named a gas scrubbing tower.

[0003] Currently, when the gas is discharged from the inlet pipe after being washed inside the scrubbing tower, it also discharges fine water mist from the air. The water mist can easily accumulate in the inlet pipe, causing water backflow and affecting the normal operation of subsequent equipment. Utility Model Content

[0004] To address the problems in the prior art, this invention provides an inlet gas distributor that prevents backflow of water from a scrubbing tower.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An inlet gas distributor for preventing backflow of water in a scrubbing tower includes a scrubbing tower body. An inlet pipe is fixed to the top of the scrubbing tower body. A grid plate is arranged between the inner walls of the inlet pipe. The bottom of the grid plate is conical. An annular absorbent cotton pad is laid at the bottom of the grid plate. A rotating block is rotatably arranged at the middle of the bottom of the grid plate. A rotating ring is rotatably arranged between the inner walls of the inlet pipe. An annular groove is formed at the top of the rotating ring near the outer edge of its surface.

[0006] Optionally, multiple pressure rollers are equidistantly arranged in the circumferential direction between the top of the rotating ring and the outer surface of the rotating block, and each of the multiple pressure rollers presses against the annular absorbent cotton pad.

[0007] Optionally, the inner wall of the rotating ring is fixed with multiple vortex blades at equal intervals along the circumferential direction, and a sealing ring is slidably engaged between the outer surface of the rotating ring and the inner wall of the inlet pipe.

[0008] Optionally, the outer surface of the inlet pipe is provided with a discharge port that extends into the interior, and the inner bottom surface of the annular groove is provided with a bend that extends into the outer surface of the sealing ring, with the bend facing the discharge port.

[0009] Optionally, a water tank is connected to one side of the bottom of the washing tower body, and a water pump is installed on one side of the water tank, with the inlet end of the water pump connected to the water tank.

[0010] Optionally, the interior of the washing tower body is provided with packing material in the middle, and a water spray nozzle is provided above the packing material inside the washing tower body.

[0011] Optionally, the outlet end of the water pump is provided with a connecting pipe, one end of which extends into the interior of the washing tower body and is connected to the water spray nozzle.

[0012] Optionally, a demister plate is provided between the inner walls of the washing tower body near the top edge, two maintenance doors are provided on the outer surface of the washing tower body, and an air supply pipe is connected to the front side of the washing tower body below the packing.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. In this utility model, the filtered gas flows to the inlet pipe after preliminary demisting by the demister plate. Inside the inlet pipe, the water inside the airflow is absorbed by the annular absorbent cotton pad. The airflow will impact with multiple vortex blades, thereby driving the rotating ring to rotate. When the rotating ring rotates, it will drive multiple pressure rollers to press and rotate along the annular absorbent cotton pad, so that the water inside the annular absorbent cotton pad is squeezed out, ensuring that the annular absorbent cotton pad is always in a water-absorbing state, and strengthening the adsorption force of water mist.

[0014] 2. In this utility model, the pressed water flows along the conical surface at the bottom of the grid plate to the annular groove at the top of the rotating ring for storage. When the rotating ring rotates, each time the bend passes the discharge port, the discharge port is connected to the annular groove through the bend, and the water stored in the annular groove is discharged and collected, preventing the water from accumulating in the annular groove and overflowing the top of the annular groove, flowing into the washing tower body and causing pollution.

Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0021] According to some embodiments of this solution, an inlet gas distributor is provided to prevent backflow of scrubbing tower water. (Refer to...) Figures 1-4 As shown, the inlet gas distributor for preventing backflow of water in the scrubbing tower includes a scrubbing tower body 1. An inlet pipe 6 is fixed to the top of the scrubbing tower body 1. A grid plate 12 is provided between the inner walls of the inlet pipe 6. The bottom of the grid plate 12 is conical. An annular absorbent cotton pad 17 is laid at the bottom of the grid plate 12. A rotating block 13 is rotatably provided at the middle of the bottom of the grid plate 12. A rotating ring 14 is rotatably provided between the inner walls of the inlet pipe 6. An annular groove 18 is provided at the top of the rotating ring 14 near the outer edge of its surface.

[0022] Please see Figures 1-4 Multiple pressure rollers 16 are equidistantly arranged in the circumferential direction between the top of the rotating ring 14 and the outer surface of the rotating block 13, and the multiple pressure rollers 16 are respectively pressed against the annular absorbent cotton pad 17.

[0023] Multiple vortex blades 15 are fixed at equal intervals along the circumferential direction on the inner wall of the rotating ring 14, and a sealing ring 19 is provided between the outer surface of the rotating ring 14 and the inner wall of the inlet pipe 6.

[0024] The outer surface of the inlet pipe 6 is provided with a drain port 7 that extends into the interior, and the bottom surface of the annular groove 18 is provided with a bend 20 that extends into the outer surface of the sealing ring 19. The bend 20 is opposite to the drain port 7.

[0025] A water tank 3 is connected to one side of the bottom of the washing tower body 1. A water pump 4 is installed on one side of the water tank 3, and the inlet end of the water pump 4 is connected to the water tank 3.

[0026] The washing tower body 1 has a packing material 8 located in the middle, and a water spray nozzle 9 located above the packing material 8 inside the washing tower body 1.

[0027] In addition, a connecting pipe 5 is provided at the outlet end of the water pump 4. One end of the connecting pipe 5 extends into the interior of the washing tower body 1 and is connected to the water spray nozzle 9. A demister plate 10 is provided between the inner walls of the washing tower body 1 near the top edge. Two maintenance doors 11 are provided on the outer surface of the washing tower body 1. An air supply pipe 2 is connected to the front side of the washing tower body 1 below the packing 8.

[0028] Through the above technical solution, the inlet gas distributor provided by this solution for preventing backflow of scrubbing tower water introduces waste gas into the scrubbing tower body 1 from the gas supply pipe 2. Inside the scrubbing tower body 1, the waste gas flows from the bottom of the packing 8 to the top. The packing 8 filters out toxic substances and particulate matter inside the waste gas. At the same time, under the action of the water pump 4, water is delivered to the water spray nozzle 9 and sprayed onto the packing 8 to improve the filtration intensity of the waste gas. After the filtered gas passes through the demister plate 10 for preliminary demisting, it flows to the inlet pipe 6. Inside the inlet pipe 6, the annular absorbent pad 17 absorbs moisture from the airflow, and the airflow impacts multiple vortex blades 15, thereby driving the rotating ring 14 to rotate. When the rotating ring 14 rotates, it drives multiple pressure rollers 16 to press and rotate along the annular absorbent pad 17, causing the water inside the annular absorbent pad 17 to be squeezed out. The squeezed water flows along the conical surface at the bottom of the grid plate 12 to the annular groove 18 at the top of the rotating ring 14 for storage. When the rotating ring 14 rotates, each time the bending port 20 passes the discharge port 7, the discharge port 7 is connected to the annular groove 18 through the bending port 20, and the water stored inside the annular groove 18 can be discharged.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0031] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
